Wrong question. The question is what percentage of energy is spent
replicating DNA. Cell division involves a lot more that's irrelevant to
the cell's DNA quantity. You might also wonder how much energy is spent
transcribing and then splicing out non-coding DNA. Yeah, some of it's
regulatory, but it would be easy to have a system in which identical
regulatory functions didn't require such otherwise useless transcription.

And I have no idea.

Well, that's easy. Pick one:
1. It's not junk. It all has a purpose we aren't smart enough to discover.
2. It's all a result of degeneration after the Fall.
3. Who are you to question God's actions?
